11 Claims.

This invention relates to windows of the sliding or double'hung type. An important object of the invention is to provide an improved frame construction which embodies a channel shaped section adapted to form the main'member of the jamb and which may have attached to it a light metal wall forming with the channel shaped section a lamb of rectangular cross section which is strong and rigid so that it will not bend or twist. The channel shaped sections are also so formed that the windows may be made up in units of desirable size for easy handling in shipment and when multiple windows are desired, they may be joined at the Job so as to form multiple units to meet the needs of the building. The jamb sections of adjacent units may be united to form hollow mullions by uniting the channel sections of the adjacent units, there being no waste of material, and it being unnecessary to remove, add or cut away any part to form the muilion.

The invention also provides for the use of clamping means for connecting the adjacent channel sections to form the mullion, the clamping means being of such nature that the two channels may be clamped together and a sealed joint formed by applying the clamp and attaching it from the outside.

Another object of the invention is to provide an improved header construction for the frame, utilizing a channel shaped member to which is attached an angle or L-shape'd member to form a tubular header strong enough to form the lintel for the window, the flange of the. angle also serving as means by which the header can be secured in the masonry wall.

Another object of the invention is to provide an improved sash construction in which the counterbalancing means are contained within the sash. Other objects and advantages of the invention will appear from the following detailed description of a preferred form illustrative of {are principles of the invention.

' In the accompanying drawing: 1

Figure 1 is a front elevation showing a series of window units mounted in a single opening in a w ll;

Figure 2 is a vertical section on line 2-201 'Figurel;

Figure 3 is a horizontal section of the window lamb and lower sash on line 3-3 of Figure l; Figure 4 is a horizontal section through the mullion taken on line 4-4 of Figure 1, the sashes and weather strips being omitted; and

Figure 5 is a pe pective view of a portion of the G-shaped clamping member. Referring to the drawing in detail, the basic member of the frame construction comprises a 5 channel shaped member ID which has a flange ll towards the inside of the building, terminating in an outwardly projecting lip l2, and which has a second flange l4 on the side towards the outside of the building, this flange having permanently secured to it by welding'or otherwise the flange forming memer ii. The member l6 terminates at its edge towards the outside of the'window opening in a lip l'l corresponding in position to the lip [2 on the flange II. The other edge of the member I terminates in a flange is having an overhanging lip 20, this flange forming an outer stop bead and providing a recess for holding a sash sealing and guiding membet to be described. The jamb member ID, including the flanges and flange forming member l6, are preferably formed of non-ferrous or non-v corrosive metal, such as aluminum, bronzeor stainless steel. An inner stop bead of similar metal is shown at and comprises a portion fitting against the channel I0 and adapted to be secured thereto by removable fastening means such as screws 26, this stop bead preferably having a short flange 21 and carrying a flange portion 28 terminating in a lip 29 adapted to receive and hold a sash sealing and guiding member to be described.

Ina double hung window such as shown, the channel member l0 also has attached to it a removable parting strip 32 which has a base 33 adapted to flt over a rib portion 34 of the channel member l0 and to be secured thereto by screws 35or in any suitable manner. The parting strip is preferably. of slightly wedge shape as shown, the side flanges of the strip diverging slightly from the base so that the contact of the sashes with the parting strip is along a narrow line.

Where the channel member I0 is used as the 'outer side jamb of a frame unit, that is as a unit which contacts the masonry wall, the jamb is completed by attaching a. plate 40 which may be of light metal, either ferrous or non-ferrous, to the two lips I 2 and I 1. The plate 40 may be secured to the lips in any suitable manner, as by rivetin welding or the like. When the plateis attached to the channel a strong and rigid tubular construction of lamb is provided. Ordinarily the frame units will be shipped to the job without the attachment of plates 40. This permits any number of frame units to be assembled to make a multiple unit. This is socomplished by placing the channel members 01' adjacent units together, as shown in Figure 4, thus forming hollow mullionsi When the channel members of adjacent units are thus placed together, it is unnecessary to use the plates 48 except at the ends of the multiple unit and a saving in metal results.

Any suitable means for securing the channel members together may be employed, but that shown in Figure 4 is particularly effective. As here shown, clamping members 45, which may be described as of roughly G-shaped cross section, are employed. These G-shaped members are fitted over the lips I! and I1 ofadjacent lamb channels which flt tightly between the outer legs 48 and the inner legs 41 of the G-shaped section. Attaching screws are then passed through registering holes in the legs and lips, the holes in the inner legs of the G-shaped members being tapped for engagement with the screws. The recesses in the G-shaped members may be fllled with a suitable sealing or packing compound such as mastic, as indicated at 58. The jamb channels are thus flrmly and tightly secured and sealed together, this being accomplished entirely from the outside of the tubular structure formed, so that there is no difliculty in uniting the parts at the job. A very strong tubular mullion structure results with no superfluous metal, as would be the case if two completely tubular jamb members were assembled back to back.

The header comprises a main channel member ill generally similar in shape to the jamb channel l8 and provided with a flange 8| terminating in a lip $2 at the inside of the window and with a flange 53 to which is attached a flange forming member 64 at the outside of the window. The flange forming member 8| has a lip 85 and a stop bead flange 66 terminating in a lip 81. In place of the removable parting strip the channel member 88 is preferably formed to provide a projection 68 between the sashes. For completing the header in tubular form a light angle iron or L-shaped section 89 is attached to the lips 82 and 55, the angle iron having an upstanding flange or leg 18 which may be built into the wall and serve as a means for securing the window in position and as a weather stop. Where a multiple unit, such as shown in Figure 1 is used, the angle iron 89 may extend across all of the window units, if desired, .and thus assist in holding them in proper alignment.

It will be seen that the masonry or other building construction descends well below the highest point reached by the flange forming member 84, and that accordingly between this member and the masonry. construction a channel is formed having as its base the lip 85, which channel is suitably adapted to receive caulking material. Similar caulking pockets occur at the side jambs of the frame, the lips I! forming the bottom of the pockets.

The window frame is shown as being providedwith a sill member 15 made of non-ferrous or non-corrosive metal, and having a downwardly projecting flange 16 at its outer edge and being formed to provide 'a shoulder 'I'I for engagement with the lower sash and with a channel 18 for reception of a resilient sealing member 19. At the inner'edge of the sill member is a horizontal flange '88 to which'is welded, or otherwise suitably secured, a stool 8| which terminates adjacent to the window sash in a lip 82 adapted to 18. The sill member is preferably formed to provide a recess 83 back of the sealing member so as to permit'the latter to be tilted for ready removal or insertion. The sill is completed by a horizontal flanged plate 85 and a vertical flanged plate 88, the outer edge of the former bein welded or otherwise secured to the flange 16 of the sill member, while the top e ge of the plate 86 is welded or otherwise secured to the under side of the flange 88. The adjacent edges of the plates 85 and 86, at the comer'of the sill, are provided with overlapping flanges which may be of L-shape as shown at 81 and 88, respectively, and are suitably secured together by welding, riveting or otherwise. The overhanging flange I8 and attached flange of the plate 85 form a pocket for caulking 80. The various backing plates '40, 89, 85-and 85,being concealed from the weather, need not be formed of nonferrous or non-corrosive material unless desired.

The sashes mounted in the frame described may be of any suitable construction, those illustrated being made of extruded metal, such as aluminum or bronze. Preferably the sashes are provided with hollow channel shaped stiles as shown in Figure 3, which are open at the outside and provide spaces to receive spring or drum type sash balances as indicated in dotted lines at I00. The sashes are provided with glass supporting ledges Illl and with overhanging putty retaining lips I02.

For sealing the sides of the sashes, resilient guiding and sealing strips are mounted in the jambs. In the construction shown, each of these comprises a base H0 shaped to seat in a recess Ill formed in the lamb member. The base carries a right angled flange H2, from the outer end of which is bent back a flexible tongue H8, adapted to bear against the side face of the sash stile. The angle of the resilient member flts behind the lip 20 which retains the resilient member in place. Extending from the opposite edge of the base H8 is a flexible tongue Ill which engages the outer edge'of the sash stile. The edge of the tongue 4 projects under the overhanging part of the base 33 of the parting strip which serves to protect the raw or the unreinforced flexible edge of the tongue and also maintains the tongue under an initial tension when the sash is not in engagement with the tongue, as shown in the upper sash receiving channel in Figure 3. The extreme edge of the tongue I 13 projects behind a shoulder 5 formed on the base 0. This engagement serves to protect the edge of the tongue H3 and also to hold the tongue under initial tension. The tongue H3 presses the sash towards the parting strip so that there is a direct metal contact between the face of the sash and the flange of the parting strip. There is also a sealing contact between the outer part of the tongue H4 and the edge of the side wall of the sash channel, and a third sealing engagement between the tongue H3 and the face ofthe sash. "The jamb members are so formed as to providerecesses I20 back of the flanges I ll of the resilient members so as to permit the resilient members to be tilted to facili-,

engage and retain the resilient sealingv member be p ided with a rubber cushion I21 which ass-mos I 3 engages the channel member I when the window is closed.

While we have'illustrated and described in detail certain preferred forms of our invention, it is to be understood that changes may be made therein and the invention embodied in other structures. We do-not, therefore, desire to limit ourselves to the speciflc construction illustrated, but intend to cover our invention broadly in whatever form its principle may be utilized. a
